Starting at the zero milepost in Baltimore, I-695, The Curtis Creek Bridge is maintained by the Maryland Transportation Authority. The route passes over the Curtis Creek River on a pair of drawbridges, which have 58 feet of vertical navigational clearance and provide access for over-sized ships from the US Coast Guard base located further upstream. 

Initially specified for galvanizing, the Maryland Transportation Authority changed the code to a paint design. The Authority thought switching to paint would provide a faster application and was unaware of the vast differences between galvanizing and paint for this particular application. Luckily the fabricator is a proponent of galvanizing and knew to suggest this maintenance-free coating for the ultimate corrosion protection.  With thousands of commuters traveling to and from their daily destinations, a paint application would not be able to provide the Transportation Authority with the coating durability and sustainability needed to meet the bridge's anticipated life cycle. A presentation of the Benefits of Galvanizing quickly changed the minds of the Authority and made hot-dip galvanizing the clear winner to the coating question of the Curtis Creek Bridge grid deck.
